Converter lock up table-2021 10R80 Ford Mustang

[TheDogFather]

Im looking at installing a Ratiotek reprogramming kit.  One of the things it does is firm up the converter lock, however they are seeing I need to change the programming so it doesnt lock until 5th gear.  Looking at the tables I assume the ones I am interested in is auF66218 for sport mode, auF66216 for drag, auF66215 for track and auF66207 for normal (base).  These are under the Lock Maps.  I also assume setting them to 10,000 rpm will prevent the lock up. Is this correct?

 

Its interesting to note that 2nd gear thru 5th wont lock up unless you are at 90% throttle in normal mode and 1000 rpm OSS.  6th thru 10th is 70% throttle.

We actually have someone working on a detailed training guide for the 10R80. There are some out there for other software packages however we also have some members here who may be able to assist, I'll ask if they can help you out. @engineermike

Yes, engineermike has been super helpful. I think like most people we just need to be pointed in the right direction. Most are looking for the same thing. How to firm and quicken shifts, eliminating flares, improving converter operation and some understanding in what parameters control those functions. Thanks!

Hi, I have not seen a 10R80 Ford yet that uses the torque converter lock maps.  The converter is either using the unlock or the slip tables.  By slip, they mean clutch-controlled slip, not converter hydraulic slip, so either the torque converter clutch is not-engaged or it's engaged and controlling to some amount of slip.  And sometimes the specified slip is 0 rpm, so it acts the same as if it were locked.

The converter slip maps are like auF66225.  To prevent the clutch from engaging, change values to 10000 or some other unobtainable number.

In case you were wondering, the slip is specified in tables like auF66168.

Hope this helps!

Couple of interesting things. First, the converter unlock 3rd gear table should read Slip table.  The slip table for 1st and 2nd gear are zero. Third gear has mostly a 4 OSS RPM slip.  4th to tenth has a mid section where the slip is zero at 50 and 100 N.m and the slips at 4 again after 100 N.m.  The sport mode unlock map is masked at 9900 rpm.  Why 10000 rpm?  Also, Im assuming any setting changes in the tables mentioned is more preference and there isnt a desired set up that works better.

I'm not following most of this.  3rd gear doesn't have its own unlock table.  

1st and 2nd are set mostly to 0 but it doesn't go into slip mode at all in 1st and only at high pedal in 2nd, so it makes sense.

For preventing things, sometimes they use 9900, sometimes 10000, and sometimes lower numbers than that.  Probably just whomever is typing them in at Ford choosing whatever high numbers they feel like.

The slip and unlock maps are generally driver preference, but they do affect fuel economy and performance.  For performance you want it locked (0 rpm slip) at WOT.  There may be some tiny fuel economy advantage at cruise allowing a tiny bit of slip but not unlocking completely.  Locking at part throttle can make it feel more connected like a manual, but also could make shifts feel jerky.

This is as is. I haven't touched it...yet.
